Electrodeposited cobaly oxides for lakaline water electrolysis

摘要

A significant factor contributing to a good performance of alkaline water electroysis is the electrocatalytic activity of the anode material. It has been shown that the use of cobaltites, usually prepared by thermal decomposition, spray pyrolysis and sputtering, results in lowering the overvoltage for the O__2 evolution reaction OER(1-4). In this work we present results related to the OER on Co oxide film, prepared by anodic deposition, from Co(NO_3)_2 aqueous solution.
